RAYIMOND E. HARD, OF FORT IHORTI-IpTEXASQASSIGNOR 0F ONE-HALF TO E. H. PHILLIPS, OF FORT WORTH, TEXAS.

AUTOMATIC ADJUSTABLE FEEDER-VALVE.

Application filed July 15, 1916.

To all whom it may concern:

Be it known that I, RAYMOND E. HARD, a citizen of the United States, residing at Forth Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Automatic Adjustable Feeder-Valves, of which the following is a specification.

My invention relates to fluid-pressurereg'ulated valves and more particularly to valves that will be automatically regulated to meet the requirement of air or other fluid and to valves which will be opened more or loss according to the requirement or need of the fluid: and the object is to provide a simple valve which can be used for various purposes.

One of the objects of the improved valve is to provide a simple device which will automatically control a supply of air to the manifold of a gasolene engine according to the need of air to dilute the explosive mixture which is passing through the manifold for increasing the compression on the motor by causing a complete combustion of the hydrocarbon elements by which thepower is increased and by which a considerable saving in fuel or gasolene is elfected.

Another advantage of the improved valve is that it can be used as a pressure regulator for gas pipes which are used to furnish gas to a burner or series of burners.

Other objects and advantages will be fully explained in the following description andthe invention will be more particularly pointed out in the claim.

Reference is had to the accompanying drawings which form a part of this application.

Figure l is a diagrammatic view of a portion of a manifold and the engine cylinders with the improved valve applied thereto. Fig. 2 is an enlarged longitudinal section of the valve. Fig. 3 is a side elevation of the valve and a section of the cutoff casing. Fig. 4.- is a side elevation of the cut-off casing. Fig. 5 is a vertical section of the valve. Fig. 6 illustrates a variation in the operating devices, showing a vertical section of the sleeve and a broken section of the valve casing. Fig. 7 illustrates the same devices in the locked position.

Similar characters of reference are used to indicate the same parts throughout the several views.

Serial No. 109,561.

The improved valve 1v is provided with an inclosing cut-ofi casing 2 which is threaded exteriorly to receive a protecting casing 3 and a lock-nut at for locking the pro-tecting casing in place. The valve 1 is also provided with a nipple 5 which is screwed into the end of the casing 2 and is adapted to be tapped into the manifold pipe 6. A lock-nut 7 is provided for locking the casing 2 at different adjustments on the nipple 5. The casing 2 has a series of ports 8 and the upper or outer end 9 is closed eX- cept for a passage of the valve stem 10 which moves freely through the part 9 and this end portion serves as a guide for the valve stem 10. The drawings show the valve in acting position. In the normal or closed position, the shoulder 11 will bear against the end 12 of the cavity in the casing 2, being held in such position by a spiral spring 13 which seats. on the end 9 and against a nut 14- which is screwed on the stem 10 and locked in position by a locknut 15. The tension of the spring 13 can be regulated by the nut 14. The valve 1 has an annular exterior groove 16 which registers with the ports 8 in the cut-off casing 2. The valve 1 has an interior cavity and ports 17 which lead from the groove 16 to the interior of the valve, the cavity of the interior forming a part of the duct for the passage of air or other fluid. The nipple 5 completes the passage into the manifold pipe.

In operation the spring 13 is set to permit the valve 1 to be closed, that is, so that the spring will close the valve 1 which is done by drawing the valve toward the interior shoulder 12 until the groove 16 will not register with the ports 8 in the cut-off casing 2. When a vacuum or partial vacuum is formed in the manifold, the pressure of the air on the valve 1 will overcome the tension of the spring 13 and bring the groove 16 to register with the ports 8 so that the air will pass into the duct in the valve and on into the manifold 6. The ports 8 may be opened to their full capacity or they may be only partly opened to permit more or less air to pass inwardly. The spring 13 can be set to control the amount of air to be let in. If there is a very great vacuum, as in first starting the engine, the groove 16 will be drawn past the ports 8 so that no air will be ad" mitted. The valve 1 will thus act automatiwhich occurs in the manifold during operation to provide a valve which acts both as a check and as a means for admitting air to supply the oxygen to the explosive mixture. The vacuum or partial vacuum will draw in all the air that is necessary to cause complete combustion of all the'fuel. This will prevent waste of fuel and much more work will be accomplished pergallon of gasolene.

Provision is made for manually controlling the admission of air. An elongated lug 18 is formed on the outer end of the projecting casing 3 and a steering rod is connected to the lug 18 by a universal joint 11'). There is an air passage through the lug 18 and air will. pass freely therethrough in sulficient quantity to permit the operation of the valve 1. The lock nut at may be set below the ports 8 and the cover 3 can be screwed down to close or partly close the ports 8 more or less and thus regulate manually the amount of air that can enter the manifold or other receptacle. The rod 20 can be extended within easy reach of the operator and pro-- vided with a handle 21 for convenience in turning the casing or cover 8. With such arrangement, the ports 8 need not be opened until after the engine starts.

Useful results are accomplished in the automatic operation of the valve because the nipple 5 can be placed low enough to permit the valve 1 to descend low enough to close the ports 8. This adjustment is very serviceable on high speed vehicles or machines because the amount of air should be reduced with increased speed to give the best results and with this valve adjustable in this manner, it will travel its entire stroke under nominal speed and having passed down far enough to close the ports, due to abnormal suction on account of the vacuum in the and preventing it from making too suddenly its entire stroke upwardly, the result being that the amount of air admittedis reduced automatically to correspond with increased speed. The spring 13 will force the valve gradually upward. This automatic adjustment is an improvement on valves used in gas or gasolene engines because the valve 1, in starting when there is a st'rong vacuum in the manifold, the valve 1 will be drawn to the top of the nipple 5, thus shutting off entirely the inward flow of air which would hinder the starting of the engine. It is apparent that sufficient air would be admitted before the valve is closed.

It is the purpose of the invention to provide a valve which can be used for the purpose of adding air or any other mixture desirable to gas, gasolene or any other combustible gas 01' fuel to automobiles or other machines or place when an addition of air or any other element will assist in gaining an economical or eflicient result.

The variations shown in Figs. 6 and 7 of the drawings includes a hollow stem or sleeve 22 and a rod 23 vertically movable therein for closing the valve 1. The rod 2 3 has a foot piece or pedal 24L for operation by the foot. The foot can be used to depress the valve and the pedal 24: has a hook 25 which can be pressed under the handle 21 to hold the valve 1 closed if necessary. The pedal can be released and a spring 26 will bring the rod 23 back to normal position.

What I claim, is,

An intake valve comprising a nipple to be tapped into a manifold pipe or other receiver, a valve inclosing member adjustably mounted on said nipple and having receiving ports in the side thereof, a valve movable longitudinally in said member and provided with ports and an annular exterior groove adapted to register with the ports of said member and having surfaces on each side of its own ports and said groove adapted to close the ports of said member, said valve having a stem projecting through the end of said member, a spiral spring on said stem, and means for varying the tension of said spring, and said nipple serving to limit the travel of said valve.

In testimony whereof, I set my hand this 7th day. of July, 1916.
